Metal Fence Wind Noise: How to Prevent Rattling From Corrugated Panels
Metal Fence Wind Noise: How to Prevent Rattling From Corrugated Panels
One concern homeowners have about corrugated metal fencing is noise — will it rattle, hum, or vibrate in the wind? The honest answer: poorly installed metal fencing can make noise. Properly installed metal fencing is silent. Here is how to ensure yours stays quiet.
Why Metal Fences Make Noise
Metal fence noise comes from three sources:
- Loose fasteners: Screws or bolts that are not fully tightened allow the panel to vibrate against the frame
- Panel flex: Large unsupported spans of thin metal can vibrate like a drum in strong gusts
- Thermal expansion gaps: Metal expands and contracts with temperature changes — if not accounted for, panels can rub against fasteners
How to Prevent Wind Noise
1. Use Pre-Framed Panels
Pre-framed corrugated panels from BarrierBoss come secured within a wood frame, which dampens vibration significantly. The wood absorbs energy that would otherwise travel through the metal sheet.
2. Proper Fastener Spacing
For unframed metal sheets, use fasteners every 12 to 16 inches along the top and bottom rails. More fastener points mean less unsupported metal to vibrate. Use screws with rubber or neoprene washers — the rubber cushion eliminates metal-on-metal contact.
3. Use Heavier Gauge Steel
Thicker steel vibrates at lower frequencies and requires stronger wind to flex. BarrierBoss uses 26-gauge steel with DualCoat finish — heavier than budget 29-gauge panels that are more prone to wind noise.
4. Add Mid-Rail Support
For panels taller than 6 feet, add a horizontal mid-rail to break up the unsupported span. This cuts the vibrating surface area in half and dramatically reduces noise potential.
5. Account for Thermal Expansion
Leave a small gap (1/16 to 1/8 inch) at fastener holes to allow for expansion without binding. Oval screw holes rather than round holes give the panel room to move silently.
Which Metal Fence Style Is Quietest?
- Pre-framed corrugated: Quietest — wood frame absorbs all vibration
- Hog wire panels: Virtually silent — open mesh offers no wind resistance
- Unframed corrugated sheets: Can be noisy if improperly installed, but silent with proper fastening
Hog wire fence panels are the best choice for high-wind areas because their open mesh design lets wind pass through rather than pushing against a solid surface.
